This is the 1.2GHz / 2MB L3 cache version. The card is labeled Sonnet Encore ST G4 1200/2M, and the original box label identifies it for Power Mac G4 AGP Graphics / “Sawtooth” systems.
The card was tested in a Power Mac G4 AGP system and is working properly at 1.2GHz.
The purple anodized heatsink has a small cosmetic mark on one fin from previous handling. Function is unaffected.According to Sonnet compatibility information, the Encore/ST G4 series was made for select Power Mac G4 tower models, including AGP Graphics / Sawtooth, Gigabit Ethernet, Digital Audio, and certain single-processor QuickSilver models. Compatibility depends on the exact machine, firmware, operating system, and installation setup, so please confirm suitability for your system before purchase.
This card is not intended for dual-processor Power Mac G4 systems and is not supported for the QuickSilver 2002 Dual 1GHz model.
Important note regarding Power Mac G4 Cube use: Sonnet made separate Cube-specific Encore upgrade models. This Encore/ST G4 card is not an official Cube upgrade. Some experienced users have adapted similar cards for Cube use with significant cooling and power modifications, but that is outside the supported configuration and is entirely at the buyer’s own risk.
Requires appropriate system firmware and Mac OS 9.2 or later / Mac OS X, depending on the target system and setup. Proper heatsink contact, cooling, and installation are critical for this type of upgrade.
Includes the processor upgrade card with heatsink/fan assembly and original box as shown. Please review all photos carefully for exact condition and included items.
This is vintage hardware for vintage Apple computers. Use of this item requires era-appropriate knowledge and compatible hardware. I am happy to answer reasonable questions, but step-by-step installation support is not provided, and compatibility with every system or modification cannot be guaranteed. Issues arising from unsupported configurations, insufficient cooling, power delivery limitations, or system modifications are outside the seller’s responsibility.
